Posting date issues

[John Oppenheimer]

"When editing a post in a ‘Draft’ status, using the full edit mode, the Publish immediately option is no longer available. Rather, it shows the date and time that was set when the Quick Edit occurred, and subsequent changes to the publish date have to be set manually. If not updated when the post is finally published, this leads to a publish date occurring in the past and can cause the post to not appear as the most recent post in your blog, if other posts were created and published after the draft was initially created."

And if I change anything in a post that has already been published, it changes the date and I need to republish rather than simply update it.
